Why a layout tree is invalid.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooManyNodes

More than MAX_LAYOUT_NODES nodes.

TooDeep

Nodes nested deeper than MAX_LAYOUT_DEPTH.

TooManyTexts

More than MAX_LAYOUT_TEXTS nodes with text.

TooManyIsolated

More than MAX_LAYOUT_ISOLATED nodes with a visual field or hidden overflow.

MixedContent

A node with more than one of children, text, and shape.

DisplayOnLeaf

display on a node with text or shape content.

ContainerFieldOnLeaf

A container field on a node with text or shape content.

RootItemField

A size, margin, position, or item field on the root.

GridFieldOnFlex(&'static str)

A grid container field (named) on a flex container.

FlexFieldOnGrid(&'static str)

A flex container field (named) on a grid container.

FlexItemFieldInGrid(&'static str)

A flex item field (named) on a grid’s child.

GridItemFieldInFlex(&'static str)

A grid item field (named) on a flex container’s child.

TooManyTracks

More than MAX_GRID_TRACKS explicit tracks on one axis.

RepeatCount

A repeat() count outside 1 to 64.

RepeatInAutoTracks

repeat() in implicit track sizes.

AutoRepeatNeedsFixedTracks

An auto-fill or auto-fit repeat beside another, or with a track (in it or beside it) without a fixed size.

GridLineOutOfRange

A grid line outside -65 to 65, line 0, or a span outside 1 to 64.

InvalidKeyframes

Keyframes that are empty, out of order, or have an unusable curve.

OutOfRange

A value that is not finite or outside its range.

LengthKeyframesDiffer

Size keyframes that mix a percent with a length.

PaintKeyframesDiffer

Paint keyframes that differ in kind, stop count, or spread.

TextKeyframesInterpolate

A text keyframe whose interpolation is not hold.
